Best Low Calorie Snacks: 20+ Picks That Actually Fill You Up

The best low calorie snacks share three things: they taste good, they keep you full, and they don't wreck your calorie budget. Whether you're in a calorie deficit, looking for something crunchy between meals, or trying to avoid the vending machine at 3 PM, the right snack can make or break your day.

This guide covers 20+ healthy snacks across every category, from whole fruits to store-bought picks. Every snack includes its calorie count so you can plan without guessing.

What Makes a Good Low Calorie Snack?

Not all low calorie snacks are created equal. A 100-calorie pack of cookies will leave you hungry 20 minutes later. A 100-calorie serving of Greek yogurt with berries can hold you for hours. The difference comes down to three factors.

Fiber slows digestion and keeps you feeling satisfied longer. The American Journal of Clinical Nutrition published a 2015 meta-analysis showing that increasing fiber intake by 14 grams per day led to a 10% reduction in calorie intake over time.

Protein is the most satiating macronutrient. A 2008 study in the same journal found that protein-rich meals reduced ghrelin (the hunger hormone) more than carbohydrate-heavy meals.

Volume matters too. High volume low calorie snacks, like air-popped popcorn or sliced cucumbers, fill your stomach without adding many calories. You can eat a large portion and stay well under 200 calories.

The best snacks combine at least two of these three factors. That's what separates a filling low calorie snack from one that leaves you reaching for more.

Best Low Calorie Fruits and Vegetables

Whole fruits and vegetables are the original low calorie snacks. They're high in water, fiber, and micronutrients. And most of them clock in under 100 calories per serving.

• Watermelon (1 cup, diced): 46 calories. Roughly 92% water, so it hydrates while you snack.
• Strawberries (1 cup): 49 calories. Good source of vitamin C and manganese.
• Cucumber slices (1 cup): 16 calories. Pair with hummus (see protein section) for a more filling option.
• Baby carrots (10 medium): 35 calories. Crunchy, portable, and naturally sweet.
• Cherry tomatoes (1 cup): 27 calories. Pop them like candy, no prep needed.
• Apple slices (1 medium): 95 calories. A medium apple has about 4.4 grams of fiber, per USDA data.
• Sugar snap peas (1 cup): 26 calories. Eat raw or lightly steamed.

Fruits and vegetables are nutrient-dense snacks that give you vitamins, minerals, and fiber for very few calories. The downside? They're not always satisfying on their own. Pair them with a protein source like nut butter, cheese, or hummus for better satiety.

Best Low Calorie Crunchy Snacks

Crunch is what most people actually crave when they reach for chips or crackers. Satisfying that crunch without blowing your calorie count is easier than you might think.

• Air-popped popcorn (3 cups): 93 calories. One of the best high volume low calorie snacks available. Three cups is a lot of food for under 100 calories. Skip the butter and use a light seasoning instead.
• Rice cakes (2 plain): 70 calories. Bland on their own, but excellent as a vehicle for toppings like cottage cheese, avocado, or peanut butter.
• Roasted seaweed snacks (1 package): 25-30 calories. Salty, crispy, and genuinely satisfying for the calorie cost.
• Celery with 1 tbsp almond butter: 108 calories. The celery provides crunch and volume; the almond butter adds healthy fats and protein.
• AshaPops popped water lily seeds (1 oz bag): 120 calories. Water lily seeds (also called makhana or fox nuts) are an ancient Ayurvedic snack that's gaining popularity in the U.S. They pop up light and crunchy, similar to popcorn but with a different texture. AshaPops makes them in flavors like Himalayan Pink Salt, Chili Lime, and Vegan Cheese. They're seed-oil-free, gluten-free, and have 4 grams of protein per bag.
• Sliced bell peppers (1 cup): 30 calories. Red, yellow, and orange peppers are sweeter than green. Great with hummus or guacamole.

The key to crunchy low calorie snacks is choosing options with built-in volume. Popcorn, water lily seeds, and raw vegetables all give you that hand-to-mouth repetition that makes snacking satisfying, without the calorie load of traditional chips.

Best Low Calorie Protein-Rich Snacks

Protein snacks are your best weapon against hunger between meals. They take longer to digest, keep blood sugar stable, and help preserve muscle mass during weight loss.

• Greek yogurt (plain, nonfat, 6 oz): 100 calories, 17g protein. Add berries or a drizzle of honey for flavor. Avoid flavored varieties that can add 10-15 grams of sugar.
• Hard-boiled eggs (1 large): 78 calories, 6g protein. Easy to meal prep on Sunday and eat all week. Portable and filling.
• Cottage cheese (1/2 cup, 2% fat): 92 calories, 12g protein. Having a comeback as a snack food. Try it with everything seasoning, cherry tomatoes, or on rice cakes.
• Edamame (1/2 cup, shelled): 95 calories, 9g protein. Buy frozen, microwave for 3 minutes, sprinkle with sea salt. Done.
• Turkey roll-ups (3 oz deli turkey + lettuce): 90 calories, 16g protein. Spread mustard on turkey slices, add a pickle spear, roll up in lettuce. Feels like a sandwich without the bread.
• String cheese (1 stick): 80 calories, 7g protein. One of the most portable protein snacks around.

I keep hard-boiled eggs and string cheese in my fridge at all times. They're the snacks I reach for when I'm actually hungry, not just bored. If you're in a calorie deficit, protein snacks should be your go-to. They do more per calorie than almost anything else.

Best Low Calorie Sweet Snacks

Sweet cravings hit everyone. You don't need to white-knuckle your way through them. These options satisfy a sweet tooth for under 150 calories.

• Frozen grapes (1 cup): 62 calories. Freeze them for at least 2 hours. They taste like tiny sorbets.
• Dark chocolate (1 square, 70%+ cacao): 55 calories. One square, savored slowly, can stop a chocolate craving in its tracks.
• Banana "nice cream" (1 frozen banana, blended): 105 calories. Blend a frozen banana until smooth. Add a teaspoon of cocoa powder if you want chocolate flavor.
• Apple slices with cinnamon (1 medium apple): 95 calories. The cinnamon adds sweetness perception without any extra calories.
• Medjool date (1 date): 66 calories. Intensely sweet and chewy. One date is usually enough to kill a sugar craving.
• Frozen yogurt bark (homemade, 1 serving): ~100 calories. Spread Greek yogurt on parchment, top with berries, freeze, break into pieces.

Frozen fruit is an underrated move. The cold temperature slows you down, so you eat more mindfully. And the natural sugars in fruit come packaged with fiber and water, which is a very different metabolic experience than processed sugar.

Best Low Calorie Store-Bought Snacks

Whole foods are ideal, but real life demands convenience. These packaged options earn their shelf space by keeping calories low without sacrificing taste or ingredient quality.

• AshaPops Popped Water Lily Seeds: 120 calories per bag, available in multiple flavors including Turmeric Garlic. Made without seed oils, non-GMO, and vegan. The Variety Pack is a good way to try several flavors at once.
• Chomps beef sticks (1 stick): 90 calories, 10g protein. Grass-fed, no sugar added. A solid portable protein snack.
• RXBARs (minis): 110 calories. Clean ingredient list, and the minis are portion-controlled so you don't eat a full bar when you only need a small pick-me-up.
• Siete grain-free tortilla chips (1 oz): 140 calories. Higher than some options here, but made with avocado oil instead of seed oils. Better ingredient quality than standard tortilla chips.
• Hu Kitchen chocolate bars (1/2 bar): ~100 calories. No refined sugar, no emulsifiers. If you want a clean chocolate fix, these are hard to beat.
• Simple Mills crackers (about 17 crackers): 150 calories. Almond-flour-based, seed-oil-free. Pair with cheese or hummus.

When choosing store-bought low calorie snacks, read the ingredient list before the nutrition label. A snack with 150 calories and clean ingredients will serve you better than a 100-calorie pack full of artificial additives. Watch out for seed oils (canola, soybean, sunflower) and added sugars listed under different names. Our complete guide to seed oil free snacks covers what to avoid and which brands to trust.

How to Choose Low Calorie Snacks That Actually Fill You Up

Filling low calorie snacks share a pattern. They're not magic. They just check more boxes on the satiety checklist.

Combine macros. A snack with protein AND fiber will hold you longer than one with just carbs. Apple slices (fiber) with peanut butter (protein + fat) is a classic example. Rice cakes (carbs) with cottage cheese (protein) is another.

Choose high volume foods. Your stomach has stretch receptors. High volume low calorie snacks like popcorn, water lily seeds, and raw vegetables physically fill your stomach, sending satiety signals to your brain. Three cups of air-popped popcorn has fewer calories than 15 potato chips, but takes up significantly more space.

Eat slowly. It takes roughly 20 minutes for satiety hormones to reach your brain after you start eating. Snacks you have to chew (raw carrots, nuts, popcorn) naturally slow you down compared to snacks you can inhale (yogurt, crackers).

Portion control still matters. Even healthy snacks add up. Almonds are nutrient-dense, but a cup of almonds is over 800 calories. Measure portions until you develop an intuitive sense of serving sizes. A single serving of almonds is about 23 nuts (164 calories, per USDA).

Low Calorie Snacks for Specific Goals

Low Calorie Snacks for Weight Loss

If you're in a calorie deficit, every calorie counts. Prioritize snacks with high protein and fiber per calorie. Greek yogurt, hard-boiled eggs, cottage cheese, and edamame should be your rotation. These protein snacks keep you full between meals so you're less likely to overeat at dinner.

Avoid "low calorie" snacks that are just smaller portions of junk food. A 100-calorie cookie pack will spike your blood sugar and leave you hungrier than before. Nutrient-dense snacks, even at slightly higher calorie counts, will serve your weight loss goals better.

Pre-Workout Snacks

You need quick energy before a workout, not slow-digesting protein. Go for simple carbs 30-60 minutes before training. A banana (105 cal), a handful of dried fruit (100-130 cal), or a rice cake with honey (85 cal) all work well. Save the protein snacks for after your workout.

Late-Night Snacks

Late-night snacking gets a bad reputation, but the timing isn't the problem. The problem is what most people eat late at night: high-calorie, high-sugar comfort food. If you're genuinely hungry after dinner, reach for something light. A cup of cottage cheese, a handful of frozen grapes, or some popped water lily seeds will satisfy the urge without adding 500 calories before bed.

On-the-Go Snacks

Portability matters when you're busy. The best on-the-go low calorie snacks don't need refrigeration and won't make a mess in your bag. String cheese (if you have a cooler), beef sticks, fruit, rice cakes, and individually packaged popped snacks are all solid choices. Pre-portioned options remove the temptation to overeat from a big bag.

FAQ: Low Calorie Snacks

What is the lowest calorie snack you can eat?

Raw celery is one of the lowest calorie snacks at about 6 calories per stalk. Cucumbers (16 cal/cup), cherry tomatoes (27 cal/cup), and sugar snap peas (26 cal/cup) are other extremely low calorie options. All of these are mostly water and fiber.

Are low calorie snacks good for weight loss?

Yes, as long as they're also nutrient-dense. Snacks high in protein and fiber, such as Greek yogurt, hard-boiled eggs, and edamame, help maintain a calorie deficit without constant hunger. A 2016 review in Advances in Nutrition found that structured snacking on high-protein or high-fiber foods did not lead to weight gain and may support weight management.

How many calories should a snack be?

Most dietitians recommend snacks between 100 and 250 calories, depending on your total daily calorie target. If you eat three meals and two snacks per day on a 2,000-calorie diet, each snack should be roughly 200-250 calories. If you snack more frequently, keep each one closer to 100-150 calories.

What snacks are under 100 calories?

Plenty of options fall under 100 calories per serving: a hard-boiled egg (78 cal), a cup of strawberries (49 cal), a string cheese stick (80 cal), 3 cups of air-popped popcorn (93 cal), a cup of baby carrots (35 cal), a cup of watermelon (46 cal), or a single Medjool date (66 cal). Snacks under 100 calories work best when you pair two of them together for a more satisfying combination.

Can you eat unlimited low calorie snacks?

No. Even low calorie foods add up. If you eat 10 servings of a 50-calorie snack, that's 500 calories. Portion control matters regardless of how healthy the snack is. Raw non-starchy vegetables (celery, cucumbers, leafy greens) come closest to "unlimited" because their calorie density is extremely low, but even then, eating mindfully is a better practice than eating without limits.

What are the most filling low calorie snacks?

The most filling low calorie snacks combine protein, fiber, and volume. Top picks include: Greek yogurt with berries (about 130 cal), cottage cheese with cherry tomatoes (about 120 cal), air-popped popcorn (93 cal for 3 cups), edamame (95 cal for 1/2 cup shelled), and hard-boiled eggs (78 cal each). These rank high on satiety because they take longer to digest and physically fill your stomach.
